I have been looking for Windows laptops from HP and Lenovo. HP confirmed that they don't have a laptop that can drive 4K display @ 60Hz, has 1TB user replaceable SSD, 14-15" screen at resolutions between 1080 and 4K (1080 is too low for professional work and the letters are too small to see under 4K in 14-15" screen), under 2kg weight and use Nvidia GPU. Ideally with around 10 hours battery life. Can' get confirmation from Lenovo yet. Know any Lenovo laptop or laptops from reputable manufacturers that fit my specifications? Why most Windows laptops don't have HDMI 2.0 port? Manufacturers just claim that their laptops have HDMI port but upon further checking, those are HDMI 1.4 rather than 2.0 port.
